[0002]

2. Description of the Related Art In an electronic musical instrument, there is known an automatic performance device capable of performing an arpeggio performance or a sequence performance based on performance of a keyboard or the like. An arpeggio performance is a method in which notes corresponding to a plurality of keys, such as a single key operated on the keyboard or a pitch key that becomes a chord, are chopped in a predetermined rhythm while these keys are pressed. This is an automatic performance in which each note is distributed. On the other hand, a sequence performance is an automatic performance in which note data of a short phrase sequence stored in advance is assigned to each key, and playback of the short sequence data is started when a key is pressed, and stopped when the key is released. It is. In either case, a note corresponding to the actual key pressed state is not normally sounded.

The above-mentioned automatic performance device has a MIDI output terminal and a MIDI input terminal. However, only note data played on the keyboard is output as MIDI data, and note data of automatically generated arpeggio or sequence performances is not output as MIDI data. For this reason, there is a disadvantage that an arpeggio performance or a sequence performance cannot be recorded on an external device for inputting MIDI data and recording and reproducing the performance, and that the performance cannot be reproduced by an external sound source device by reproducing the performance data. . In order to record an arpeggio performance or the like on an external device, the generated note data of the arpeggio performance or the like may be output as MIDI data together with the keyboard performance note data. However, if note data output as MIDI data is recorded, and the recorded note data is again input to an automatic performance device capable of performing arpeggio performance and the like, and an attempt is made to reproduce the original performance,
This time, there is a problem that note data generated by an arpeggio performance or the like is further subjected to an arpeggio performance or the like, resulting in a performance different from the original performance and a strange performance.

Further, note data of an arpeggio performance or the like is added to note data of a keyboard performance and M
Even if the user tries to reproduce and edit the IDI data later, there is also a problem that the editing work is troublesome because both are mixed. As described above, there are various problems in outputting note data generated by an automatic performance such as an arpeggio performance to MIDI.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and has been described in which note data of an automatic performance generated in response to operation of a performance operator such as a keyboard is transmitted to an external device. It is an object of the present invention to provide an automatic performance device that can be reproduced without causing inconvenience.

[0006]

According to the first aspect of the present invention, in an automatic performance apparatus, note data generating means for generating note data based on operation of a performance operator, and output of the note data generating means. Note data generating means for generating note data in a predetermined automatic performance pattern based on note data of at least a part of the note data in the note data to be played, and note data output by the note data generating means and the note data generating means. It has note data output means for allocating note data to be output to a different output channel and outputting it to an external device. Therefore, since both note data based on the operation of the performance operator and note data of the automatic performance are output, both the performance by the performance operator and the automatic performance such as arpeggio and sequence performance are recorded and reproduced on an external recording / reproducing device. can do. In addition, the output channel of the note data based on the operation of the performance operator and the output channel of the note data of the automatic performance are made different, so that after recording on an external recording / reproducing device, it can be automatically played on the external performance device. it can. That is, the external performance device having the automatic performance function selects the output channel of the note data based on the operation of the performance operator, and the external performance device without the automatic performance function outputs the output channel of the note data of the automatic performance. By selecting, the original automatic performance can be reproduced. Also, the editing operation becomes easy.

According to a second aspect of the present invention, there is provided the automatic performance device according to the first aspect, further comprising note data input means, wherein the note data generation means includes a note data output from the note data generation means. Generating note data in the predetermined automatic performance pattern based on at least one of note data of at least a part of the note range and note data of at least a part of the note data output from the note data input means. Is what you do. Therefore, when the note data of the original performance based on the operation of the performance operator recorded on the external recording / reproducing device is reproduced on the external recording / reproducing device and input to the note data input means of the automatic performance device, The note data generating means can reproduce the original performance based on the note data without any inconvenience. Further, when the note data generating means also inputs the note data output by the note data generating means, the performance based on both the note data becomes possible.

According to a third aspect of the present invention, in the automatic performance apparatus according to the first or second aspect, both the note data output by the note data generating means and the note data output by the note data generating means are provided. A tone signal forming means for forming a tone signal based on the tone signal; In the automatic performance device, a musical tone formed based on the note data output by the note data generating means and a musical tone formed based on the note data output by the note data generating means have the same timbre.
Normally, when note data for one tone is output to an external device, the note data is output on one output channel. However, in the present invention, even if note data for one tone is generated, the source of the note data is one. If they are different, they are output on different output channels. For this reason, both note data can be separately recorded and reproduced by an external recording and reproducing device.

BEST MODE FOR CARRYING OUT THE INVENTION The automatic performance device of the present invention can take various performance states according to a sound source mode, an automatic performance mode such as an arpeggio performance / step sequence performance, and a keyboard mode. Some of them are exemplified below.
FIG. 1 is an explanatory diagram of a first state of an arpeggio performance according to an embodiment of the present invention. In the figure, 1 is a keyboard, 2 is a coupling unit, 3 is an arpeggiator, 4 is a first sound source sequence, and 5 is a second sound source sequence. This explanatory diagram is a functional configuration diagram showing how note data is transferred between functional components, and a connection line indicates a flow of the note data.

The keyboard 1 outputs note data corresponding to the pitch of an operated key. This note data is MID
The data is combined with the note data input from the I-input channel C by the combining unit 2 and input to the arpeggiator 3. The arpeggiator 3 generates note data in a predetermined arpeggio pattern based on the note data, outputs the note data to the first tone generator series 4, and reproduces a tone from the sound system. The sound source also includes the second sound source sequence 5, but in this state, only the first sound source sequence 4 is used. The note data from the keyboard 1 by the keyboard performance is output to the MIDI output channel A, and the arpeggio performance note data generated by the arpeggiator 3 is output to the MIDI output channel B.

In the above description, the combining section 2 has a function of transmitting note data input from a plurality of paths onto one path, but the input section of the arpeggiator 3 has this combining function. You may let it. In the case where note data is not input from the MIDI input during a performance by operating the keyboard 1, the coupler 2 can be used as a simple signal switching unit. The output of the keyboard 1 is the arpeggiator 3 and the MIDI output channel A.
However, note data may be individually output from the keyboard 1 in a format corresponding to each output destination. The same applies to the branch of the output of the arpeggiator 3.

FIG. 2 is a block diagram of an embodiment of the present invention.
FIG. 4 is an explanatory diagram of an example of a setting state of an IDI channel. M
As the IDI output channel, two systems of channels A and B can be set. For channels A and B, different channels are set from 16 channels. In this embodiment, the output of the keyboard 1 is set to channel A, and the output of the arpeggiator 3 is set to channel B.
In the case of a step sequencer to be described later, channel B is set for the output. The MIDI input channel can be set to two channels of channels C and D, and a channel is set from 16 channels.
In the embodiment shown in FIG. 1, channel D is not used.

Returning to FIG. 1, the first state of the arpeggio performance will be described. In this state, the tone generator mode selects the single mode of the first tone generator series, and the automatic performance mode is the arpeggio playing mode for designating the first tone generator series. Therefore, the arpeggiator 3 is set to the first tone generator series. ing. The keyboard mode of the keyboard 1 is a normal mode in which all keys perform the same operation. The sound source modes include a single mode of either the first sound source sequence or the second sound source sequence, and a dual mode for simultaneously selecting both sound source sequences. These are selected by a user using a panel switch (not shown). On the other hand, setting of the keyboard mode, first and second
Setting of the tone to the sound source series 4 and 5, setting of automatic performance such as arpeggiator / step sequence, and
The setting of the sound source sequence generated in the automatic performance mode is stored for each voice as a voice (tone color) parameter, and is set in conjunction with the selection of the voice (tone color) by a user using a panel switch (not shown). . Therefore, the selection of the sound source mode is effective for the sound source sequence selected according to the voice. In this embodiment, since the arpeggiator 3 is set to the first sound source sequence 4, the user presses one key on the keyboard 1.
Alternatively, when a plurality of keys are pressed simultaneously, the first sound source sequence 4
, An arpeggio performance sound is generated, and an arpeggio performance sound is generated from a sound system (not shown).

FIG. 3 is an explanatory diagram showing an example of an arpeggio performance pattern according to an embodiment of the present invention. When simultaneously operating three keys, for example, a chord key, the notes corresponding to the plurality of keys are sequentially arranged in a predetermined pattern, for example, as shown in FIGS. The dispersed sound is repeated according to a pattern such as up, down, up / down A, up / down B as shown in d), or a pattern including a rest (not shown), a random pattern, or the like. This pattern is sequentially generated at the pitch of a key that has been depressed almost simultaneously, but depending on the type of arpeggio pattern, the pitch is changed to a pitch having the same pitch one or two octaves higher. In some cases, a pattern consisting of six to nine tones is generated in the case of three keys. Conversely, when only one key is operated, the tone of the key corresponding to this key is repeated, or depending on the type of the arpeggio pattern, the tone is one or two octaves higher than the operated key. The sound is dispersed while mixing.

On the other hand, the step sequence performance is an automatic performance in which a single key is pressed to produce a short sequence pattern of notes of a plurality of steps (for example, up to 16 steps) when one key is pressed. As the sequence pattern, a step length indicating how many notes one step corresponds to, and a pitch of each step are set. Note that more detailed setting information can be included in the sequence pattern. For example, a gate time is set for each note to determine the degree of staccato. The gate time indicates the actual sounding duration of each note, and is represented by an absolute time (for example, the number of clocks of each note. The clock is a minimum unit of the note) and a relative time (for example, relative to the step length). Ratio). If it is desired to give a swinging feeling of a swing performance often performed in jazz, an amount for shifting the sounding start time of the even-numbered beat is set. In this step sequence performance, a plurality of performance parts may be simultaneously reproduced in response to operation of one key. In this case, if the note data of each part is output independently on a different MIDI channel, the side receiving the MIDI data,
It is convenient because a part can be arbitrarily selected.

The MIDI data output from the MIDI output channels A and B can be recorded by an external device capable of recording and reproducing MIDI data. The reproduced MIDI data can be reproduced to reproduce an arpeggio performance with an external sound source. Is possible. That is, when the external device is an automatic performance device provided with an arpeggiator, channel A may be selected and input to the arpeggiator. On the other hand, when the external device does not include the arpeggiator, the channel B may be selected and input to the sound source. Alternatively, if channel A is selected and input to the sound source, the original keyboard performance can be reproduced. When both the channels A and B are input to the sound source, the tone of the original note data obtained by playing the keyboard is reproduced in duplicate. There is no particular limitation on the method of recording and reproducing the automatic performance data, and a format in which data of a plurality of channels are mixed in one track or a format in which data of each channel is divided for each track may be used. .

The MI recorded by an external device as described above
The DI data can be reproduced and reproduced by the automatic performance device of this embodiment. The note data of the MIDI output channel A is once recorded by an external device, reproduced and input through the MIDI input channel C of the device, and the note data is input to the arpeggiator 3 via the coupling unit 2. The characteristics of the external sound source device may be different from the characteristics of the sound source device of the automatic performance device of the present embodiment, and when using the external sound source device, it is not always possible to reproduce exactly the same musical tone. , M
By inputting IDI, it is possible to reproduce exactly the same arpeggio performance. In this embodiment, there is no response even if any note data is input to the MIDI input channel D.

Note that when note data is output by operating the keyboard 1 and note data is also input from the MIDI input channel C, the two note data are combined via the combining unit 2. The arpeggiator 3 performs an arpeggio performance based on both note data.

As described above, both the note data by the operation of the keyboard 1 and the note data of the automatic performance are output, so that both the performance by the operation of the keyboard 1 and the arpeggio performance can be output to an external recording / reproducing device or the like. It can be recorded and reproduced. Moreover, since the MIDI output channel of the note data by the operation of the performance operator and the MIDI output channel of the note data of the automatic performance are made different, after the note data by the operation of the performance operator is recorded on the external recording and reproducing apparatus, The original performance can be reproduced without inconvenience by reproducing and re-inputting to the automatic performance apparatus. The original arpeggio performance can be reproduced without using the automatic performance device by recording the note data of the automatic performance on an external recording / reproducing device and then reproducing and inputting the data to an external sound source device or the like. .

FIG. 6 is an explanatory diagram of a second state of the arpeggio performance according to the embodiment of the present invention. In the figure, FIG.
The same reference numerals are given to the same parts as those described above, and the description is omitted. 4
Reference numeral 1 denotes a connecting portion similar to the connecting portion 2 shown in FIG. In this second state of the arpeggio performance, the sound source mode is single, and in this example, the first sound source sequence is selected. In this example, the arpeggiator 3 is set to the first sound source sequence 4 in conjunction with the selection of the voice. The keyboard mode is Arpeggio / Normal, with the left key below the split point (SP) serving as an arpeggio playing key and the right key above the split point (SP) serving as a normal normal playing key. Here, the split point (SP) is for causing the keyboard to have different operation functions between a left keyboard region at a lower pitch and a right keyboard region at an upper pitch with a predetermined pitch as a boundary. The split point (SP) is preset in advance, but can be freely set by the user.

Note data corresponding to a key operated below the split point (SP) operated on the keyboard 1 is MIDI data.
From the note data input from the input channel C, the data is combined with the note data corresponding to a key below the split point (SP) by the combining unit 2 and input to the arpeggiator 3. On the other hand, note data corresponding to a key at or above the split point (SP) operated on the keyboard 1 is output to the combining unit 41. Arpeggiator 3
Generates note data in a predetermined arpeggio pattern based on the note data from the combining unit 2 and outputs it to the combining unit 41. The note data corresponding to the key at or above the split point (SP) from the note data input from the MIDI input channel C is also input to the combining unit 41, and the output of the combining unit 41 is the first sound source. The sound is output from the sound system to the stream 4 and reproduced. The sound source is
Although the second sound source sequence 5 is also provided, in this state, since the sound source mode is single and the first sound source sequence is selected, the second sound source sequence is not used.

Therefore, the split point (SP)
By operating the key less than the key, an arpeggio performance sound of the tone set from the first tone generator series 4 is generated, and a tone mixed with the normal performance sound by operating the key above the split point (SP) is generated. Occur. In this example, the arpeggio performance sound and the normal performance sound are produced by the same sound source sequence. Note data from the keyboard 1 by the keyboard performance is split point (SP)
Everything, including less than, is output to MIDI output channel A, and the arpeggio performance note data generated by the arpeggiator 3 is output to MIDI output channel B. Whether the note data is less than or equal to the split point (SP) is determined by the keyboard 1 and the MIDI input means, and an output destination corresponding to each is determined.
It is also possible to make a determination on the 41 side and input a desired one.

M from MIDI output channels A and B
It is possible to record the IDI data in an external recording / reproducing device, reproduce the same, and reproduce an arpeggio performance with an external sound source. If the external device is an automatic performance device equipped with an arpeggiator, the MID of channel A
I data is used. If the external device does not have an arpeggiator, both reproduced channels A and B may be selected and input to an external sound source. Channel A
Since the note data obtained from the Arpeggiator includes the note data on which the arpeggio was played, when input to an external sound source together with the note data obtained from channel B, the note data on which the arpeggio was based on the original performance The performance is as if a musical tone was added. If you want to reproduce the same performance as the original performance, set the external automatic performance device so that when inputting note data obtained from channel A, note data below the split point is not taken in or recorded. You can delete it later. For an apparatus not equipped with an arpeggiator, the automatic performance apparatus uses the keyboard 1 to store note data below the split point.
Channel A after removing it from the note data from
It is also possible to provide an output mode in which the data is output to

In order to reproduce the note data recorded by the external device and reproduce the note data by the automatic performance device of this embodiment, only the note data of channel A recorded by the external device is transmitted from channel C of the MIDI input. When you enter
Exactly the same arpeggio and normal performances can be reproduced.

FIG. 7 is an explanatory diagram of a third state of the arpeggio performance according to the embodiment of the present invention. In the figure, FIG.
The same reference numerals are given to the same parts as those described above, and the description is omitted. 5
Reference numeral 1 denotes a connecting portion similar to the connecting portion 2 shown in FIG. In this third state of the arpeggio performance, the sound source mode is the dual mode, and the first and second sound source sequences 4 and 5 are selected. The keyboard mode is a normal mode. The arpeggiator 3 is set to the first sound source sequence 4.

The note data corresponding to the pitch of the key operated on the keyboard 1 is input to the arpeggiator 3 via the combining section 2 together with the note data input from the channel C. The arpeggiator 3 generates note data in a predetermined arpeggio pattern based on the note data from the combining unit 2 and outputs the note data to the first sound source sequence 4. At the same time, keyboard 1
The note data corresponding to the pitch of the key operated by the user is combined with the note data input from the channel D by the combining unit 5.
1 to the second sound source sequence 5. 1st, 2nd
Are reproduced from the sound system in combination. Therefore, in this example, an arpeggio performance sound is generated from the first sound source sequence 4, a normal performance sound is generated from the second sound source sequence 5, and the arpeggio performance sound and the normal performance sound are generated in different tones. Will be.

The note data from the keyboard 1 is output to the MIDI output channel A, and the arpeggio performance note data generated by the arpeggiator 3 is M.
It is output to channel B of the IDI output. It is possible to record the note data of channels A and B in an external recording / reproducing device, reproduce the same, and reproduce the arpeggio performance with an external sound source. That is, when the external device is an automatic performance device provided with a step sequencer, MIDI data of channel A is used. If the external device does not include a step sequencer, channel B may be input to the first sound source sequence of the external sound source, and channel A may be input to the second sound source sequence 4. Also,
If the note data of channel A recorded by an external device is reproduced and input to both MIDI input channels C and D, it is possible to reproduce exactly the same arpeggio performance. Channels C and D may be set to the same channel.

The state of the arpeggio performance has been described above. In addition to the above-described states, a mode in which the arpeggio performance is allocated to only the second sound source series, and "BOTH" in which both the first and second sound source series are allocated. Mode, the arpeggio performance function does not work.
F "mode. When the arpeggio performance is set to the first sound source sequence 4 and the sound source mode is the single mode for selecting the second sound source sequence, the arpeggiator 3 does not work. On the other hand, when the “BOTH” mode is set, the arpeggiator 3 operates if the sound source mode is a single mode for selecting one of the first and second sound source sequences 4 and 5. In this case, if the sound source mode is the dual mode, the arpeggiator 3 operates for the first and second sound source sequences 4 and 5. In addition to these, the operation state also changes according to the keyboard mode. The keyboard mode also has a split mode.
In this mode, the timbre is made different at a split point (SP). For example, note data of the left keyboard uses the first tone generator sequence, and tone data of the right keyboard uses the second tone generator sequence. Generate. As described above, there are many operation states according to the combination of each mode.

FIG. 8 is an explanatory diagram of a first state of the step sequence performance according to the embodiment of the present invention. In the figure, the same parts as those in FIGS. 1 and 6 are denoted by the same reference numerals, and the description is omitted. 61 is a step sequencer. The overall configuration is the same as that of the second state of the arpeggio performance described with reference to FIG. 6, except that the automatic performance function is replaced by the arpeggiator 3 and the step sequencer 61. The sound source mode is a single mode. In this example, the first sound source sequence 4 is selected. Further, the step sequencer 61 is set to the first sound source sequence 4. The keyboard mode is a pattern select / normal mode. A step sequence pattern is selected by operating a key below the split point (SP), and a normal performance sound is generated by operating a key above the split point (SP). The performance sound and the normal performance sound are mixed and sounded by the same first sound source sequence 4.

The note data from the keyboard 1 is all MID
It is output to channel A of I output. The note data of the step sequence performance generated by the step sequencer 61 is output to the MIDI output channel B. M
It is possible to record the MIDI data of the channels A and B of the IDI output in an external device capable of recording and reproducing, reproduce the MIDI data, and reproduce the step sequence performance with an external sound source. In other words, if the external device is an automatic performance device equipped with a step sequencer,
IDI data is used.

If the external device does not have a step sequencer, both channels A and B may be input to the external sound source. However, note data obtained from channel A includes note data for selecting a step sequence pattern. Therefore, when input to a sound source together with note data obtained from channel B, the original performance is restored to the original performance. The performance is as if note data was added. If you want to reproduce the same performance as the original performance, set the external automatic performance device so that when inputting note data obtained from channel A, note data below the split point is not taken in, or after recording. Just delete it. Alternatively, for an apparatus not provided with a step sequencer, it is possible to provide an output mode in which note data below the split point is removed from note data from the keyboard 1 and then output to channel A.

To reproduce the note data recorded by the above-mentioned external automatic performance apparatus and reproduce it by the automatic performance apparatus of this embodiment, the channel A recorded by the external automatic performance apparatus is used.
Is input from the MIDI input channel C, it is possible to reproduce exactly the same performance including the step sequence performance and the normal performance. In this use mode, there is no response even if any note data is input from the MIDI input channel D.

FIG. 9 is an explanatory diagram of a second state of the step sequence performance according to the embodiment of the present invention. In the drawings, the same parts as those in FIGS. 1, 6, and 8 are denoted by the same reference numerals, and description thereof will be omitted. Reference numeral 71 denotes a note shift unit. The overall configuration is the same as in the first state of the step sequence performance described with reference to FIG. In this example, the first sound source sequence 4 is selected.
Further, the step sequencer 61 is set to the first sound source sequence 4. However, the keyboard mode is pattern select / note shift. Split point (SP)
A key less than the key selects a step sequence pattern, but a key operation at or above the split point (SP) specifies a note shift amount of the step sequence performance instead of performing a normal performance. As a result, the performance sound of the step sequence pattern in which the pitch is shifted upward or downward from the preset reference pitch is generated by the first sound source sequence 4.

The note data from the keyboard 1 is all MID
It is output to channel A of I output. Note shift section 7
The note data of the step sequence pattern output from 1 is output to MIDI output channel B.
The MIDI data of the MIDI output channels A and B can be recorded and reproduced on an external device capable of recording and reproducing, and the step sequence performance can be reproduced by an external sound source.
That is, when the external device is an automatic performance device having a step sequencer and a note shift unit, the MIDI data of channel A is used.

If the external device does not have a step sequencer and a note shift section, note data from channel B may be input to the sound source. To reproduce the note data recorded by the external automatic performance device described above and reproduce the note data by the automatic performance device of this embodiment, only the note data of channel A recorded by the external device is input from the MIDI input channel C. It is possible to reproduce exactly the same performance including the step sequence performance and the normal performance. In this use mode, there is no response even if any note data is input from the MIDI input channel D.

FIG. 10 is an explanatory diagram of a third state of the step sequence performance according to the embodiment of the present invention.
In the drawings, the same parts as those in FIGS. 1, 6, and 8 are denoted by the same reference numerals, and description thereof will be omitted. The generation of a tone from the first sound source sequence 4 is the same as the first state of the step sequence performance described with reference to FIG. Further, the step sequencer 61 is set to the first sound source sequence 4. The keyboard mode is pattern select / normal. However, the tone generator mode is a dual mode, similar to the third state of the arpeggio performance described with reference to FIG. 7, and note data from the keyboard 1 and note data from the MIDI input D are combined by the combining unit 51. They are combined and output to the second sound source sequence 5. Therefore, the first sound source sequence 4
, A step sequence performance sound is generated by a key below the split point (SP), and a normal performance sound is generated by a key above the split point (SP). Further, from the second sound source series, a normal performance sound is generated by all keys (below the split point + over the split point).

The note data from the keyboard 1 is all MID
It is output to channel A of I output. The note data generated by the step sequencer 61 is output to the MIDI output channel B. It is possible to record MIDI data of MIDI output channels A and B in an external recording / reproducing device, reproduce the same, and reproduce a step sequence performance with an external sound source.

That is, when the external device is an automatic performance device equipped with a step sequencer, the channel A
MIDI data is used. If the external device does not include a step sequencer, channel A may be input to the first and second sound source sequences and channel B may be input to the first sound source sequence 4 of the external device. In this case, channel A
Includes note data for selecting a step sequence pattern. Therefore, when it is desired to reproduce the same performance as the original performance, when the external automatic performance device inputs the note data obtained from channel A to the first tone generator system 4, the note data below the split point is taken in. You can set it to not exist or delete it after recording. For a device not provided with a step sequencer, it is possible to provide an output mode in which note data below the split point is removed from note data from the keyboard 1 and then output to channel A. In this case, Note data below the split point is not input to the second sound source sequence 5.
If it is desired to reproduce the same performance as the original performance, another channel may be provided as the MIDI output, and only the note data above the split point may be output from the newly provided channel.

In order to reproduce the note data recorded by the above-described external device and reproduce the note data by the automatic performance device of this embodiment, the note data of channel A recorded by the external device is transmitted to channels C and D of the MIDI input. When input, it is possible to reproduce the exact same step sequence performance. Channels C and D may be set to the same channel.

The description of the state of the step sequence performance is completed above. In addition to the above-described state, similarly to the state of the arpeggio performance, a mode in which the step sequencer 61 is assigned only to the second sound source series, "BOTH" assigned to both of the sound source series, and "OFF" in which no step sequence performance is performed without assignment to either. When the step sequencer 61 is set to the first sound source sequence 4 and the sound source mode is the single mode and the second sound source sequence is selected, the step sequencer 61 does not operate. In contrast,
When the step sequencer 61 is set to “BOTH”, the step sequencer 61 operates even when the sound source mode is single and the second sound source sequence 5 is assigned, and if the sound source mode is dual, , The first
The step sequencer 61 operates in both the second sound source sequences 4 and 5. In addition to these, as in the case of the arpeggio performance, the operation state changes depending on the keyboard mode or the sound source mode, and there are many operation states depending on the combination of each mode.

FIGS. 11 to 13 are flow charts for explaining the flow of processing according to an embodiment of the present invention. FIG. 4 shows the main processing routine of the automatic performance apparatus.
The key event processing and the MIDI input processing are executed by interruption of the timer 19 at a constant time of about 10 ms shown in FIG. Only the case of the processing of the arpeggio performance is shown, and the details of the processing when the sound source mode is the dual mode or the split mode are omitted.

The key event processing shown in FIG.
At 81, it is determined whether there is a key event.
If there is no key event, the process returns and the interrupt ends. If there is a key event, S8 in FIG.
Processing proceeds to 4. The MIDI input processing shown in FIG.
In S82, it is determined whether or not there is note data in the MIDI input channel C. If there is no note data, details are omitted, but note data detection processing of other MIDI input channels and data corresponding thereto are performed. Perform processing and return.

The processing shown in FIG. 13 is common to the key event processing and the MIDI input processing. If the sound source mode is the single mode in S84, the process proceeds to S85.
In the case of the dual mode as described with reference to FIG. 7, for example, the process proceeds to S86, and in the case of the split mode, the process proceeds to S87. After each process, the process returns. . Dual mode,
Details of the processing in the split mode are omitted. S8
In step 5, it is determined whether the keyboard mode is the normal mode or the arpeggio / normal mode. If the keyboard mode is the normal mode, the process proceeds to step S89.
If the mode is the arpeggio / normal mode as shown in FIG. 6, the process proceeds to S88.

In S89, it is determined whether or not the arpeggiator is on by specifying the voice data described with reference to FIG. 5. If it is on, the process proceeds to S90, and if it is off, The process proceeds to S95. S
At 90, it is determined whether or not the selection sequence of the sound source by the sound source mode selection switch on the panel is the same as the sequence set for the arpeggiator in the voice data. If the selection sequence is the same, the process proceeds to S91. If not, the process proceeds to S95. In the case of the first state of the arpeggio performance described with reference to FIG. 1, the process proceeds to S91. As the set sequence of the arpeggiator, one of the first sound source sequence, the second sound source sequence, and both sound source sequences (= BOTH) is set in the voice data described with reference to FIG.

In S91, a process for generating an arpeggio sound is performed, and the process proceeds to S92. Since the generation process of the arpeggio sound is known, the details are omitted. In S92, the arpeggio note data is stored in FIG.
Are output to the selected sequence of the sound source in the sound source circuit 21 (the first sound source sequence 4 in FIG. 1), and the process proceeds to S93. A step S93 outputs the note data of the arpeggio performance sound to the MIDI output channel B, and the process proceeds to a step S94.

On the other hand, in S88, which has proceeded from the determination processing in S85 due to the arpeggio / normal mode, it is determined whether or not the note data is equal to or greater than the split point (SP).
If it is less than S, as in the case of the normal mode, S
The process proceeds to S89, and if it is equal to or greater than the split point (SP), the process proceeds to S95.

At S95, which proceeds from the determination processing of S88, S89, and S90, the processing is the same as that of the ordinary performance performed on the keyboard, and the key press operation is performed without generating the note data of the arpeggio performance sound. The note data is output to the specified one of the first and second sound source sequences 4 and 5 of the sound source, and the process proceeds to S94. On the other hand, when the note data of the arpeggio performance sound is generated in S91, the note data according to the ordinary performance performed on the keyboard is not generated because the note data by the key pressing operation is not output to the tone generator series.

In S94, note data resulting from a key depression operation on the keyboard is output to MIDI output channel A, and the routine returns. Therefore, in any of the arpeggio performance and the normal performance, the note data by the key pressing operation is output on the channel A by MIDI. It should be noted that the processing in the case of the step sequence performance can be realized by a similar processing, and the selection of the arpeggio performance or the step sequence performance is determined by the “arpeggio / step sequence selection” stored in the voice data shown in FIG. Data ".

In the above description, the channels A and B, which are the MIDI output channels for the keyboard performance, are set to different channel numbers, however, they may be set to the same channel number. In this case, instead of reproducing the same state as in the original performance without contradiction, the performance is aimed at another performance effect. Therefore, in a case where the user can freely set channels A and B, when the user sets channels A and B to the same channel number, a warning sound or a warning display may be performed. Also, an output mode in which automatic performances such as arpeggio performances and step sequence performances are not output as MIDI data is provided.
An output mode may be provided. As for the MIDI terminal, one terminal is used for each input and output, and it is usual to set 16 MIDI channels among them. However, a plurality of terminals, for example, two terminals are prepared, and a total of 16 channels are provided. Alternatively, 32 channels may be set.

In the above description, an example of an automatic performance such as an arpeggio performance or a sequence performance accompanying a key depressing operation of a keyboard has been described. However, a pitch pattern stored in advance in the performance progression is advanced by operating a performance operator. So-called "one-key play" may be applied to the automatic performance in the present invention. That is, note data generated by keyboard operation is output as MIDI data on channel A, and note data based on pitch data sequentially read from the memory based on the note data generated by keyboard operation is output as MIDI data on channel B. Is also good.

In the above description, a keyboard instrument with an automatic performance device has been described, but an electronic musical instrument in the form of a stringed instrument type, a wind instrument type, a percussion instrument type, or the like may be used. Further, the present invention is not limited to an electronic musical instrument in which all the performance operators such as a keyboard, a sound source device, an automatic performance device, etc. are incorporated, but each device is a separate device.
An electronic musical instrument in which the devices are interconnected using an I interface, a communication interface of various networks, or the like may be used.

The present invention is not limited to the form of a dedicated electronic musical instrument such as an electronic musical instrument with an automatic performance device, but may be a device in which application software for generating musical sounds is installed in a general-purpose personal computer. That is, a device in which each function of the hardware configuration described with reference to FIG. 4 is realized by a hardware configuration of a personal computer and application software for generating a musical tone is installed in the hardware configuration may be used.

The keyboard 12 and the switch 16 shown in FIG.
Can be replaced with a keyboard or mouse of a personal computer. However, the operability of the keyboard 12 is better when an external keyboard is used. The display circuit can be replaced with a display of a personal computer. The sound source circuit 21 and the effect circuit 22 are configured by using an external sound source device or by attaching a sound board with a built-in sound source.

A device using a so-called “soft sound source” that performs processing up to generation of a musical tone waveform by the CPU 18 and an application software program may be used. A "soft sound source" can be executed if a CODEC is attached to the basic configuration of a normal personal computer and a CODEC driver having a waveform reproducing function is installed in the operating system of the computer. The CODEC referred to here is an LSI for a voice interface, and internally includes an A / D converter, a D / A converter, a sampling cycle generator, a waveform compression / expansion circuit, a DMAC (direct access memory controller), and the like. It is a semiconductor chip. The sound system 23 shown in FIG. 4 uses an amplifier and a speaker built in or external to the personal computer. The application software is stored in a storage medium such as a magnetic disk, an optical disk, or a semiconductor memory and stored in the external storage device 24 shown in FIG.
The program is read into the AM 14 and executed. Alternatively, the information may be supplied from the server computer 29 via the communication network 28.

[0067]

As is apparent from the above description, according to the present invention, both the note data of the keyboard performance and the note data of the arpeggio and the sequence performance are output as MIDI, so that the keyboard performance, the arpeggio and the sequence are output. There is an effect that both of the performances can be recorded and reproduced in the external device. In addition, the MIDI output channel for note data played by the keyboard and the MIDI output channel for note data used for arpeggios and sequence performances are made different. After recording on an external device, only the note data played on the keyboard is sent to the automatic performance device. By inputting, there is an effect that the original performance can be reproduced without inconvenience. In addition, there is an effect that the editing work is facilitated when the performance data including both the note data of the keyboard performance and the note data of the arpeggio and the sequence performance is recorded and reproduced and edited later.
